Determination of the transmission capacity of a 500-kV line equipped with flexible electric power transmission devices

Abstract

Hydro power plants in the Russian Far East are situated far from the main power consumers. This paper considers the possibilities of increasing the transmission capacity of long 500-kV lines using reactive power compensation devices. The approach is based on the technology of flexible ac transmission systems (FACTSs). A comparative evaluation of the influence of FACTS devices such as controlled shunt reactors, static thyristor compensators, and reactive power static compensators on the line transmission capacity is carried out.
